The hex color #043989, also known as Congress Blue, presents significant accessibility challenges due to its low luminance. Its contrast ratio against white is insufficient, making it difficult for users with visual impairments to read text or distinguish elements rendered in this color. To improve accessibility, consider using lighter shades for text on a #043989 background, or pairing it with high-contrast colors like white or yellow. Tools like contrast checkers can help determine if a color combination meets WCAG (Web Content Accessibility Guidelines) standards. Proper color contrast ensures readability and usability for individuals with varying visual abilities, including those with low vision or color blindness. Using this color requires careful consideration of foreground and background combinations to avoid excluding users and to make the design accessible to a broader audience. Ensuring sufficient contrast should be a priority when designing with #043989, or any dark color, to avoid accessibility barriers.
